OldSkool,
All '65s and '66s have that depression.  It's where they filed the white or gray overlay down to expose the green or brown underlay creating a double light overlay.

Yea, my 66's have it but they just don't seem as "deep" as in his pics when I first looked at them.

That depression isn't very deep at all, the light in the picture makes it look that way....

I have a '64 with hardly a depression at all or at least you can hardly feel it.  My '65 is slightly more pronounced but the '66 is the deepest of the three.
